I believe that shaders create polygons in the process of rendering a picture on the screen , I could be wrong but I have included a couple of links that may or may not help. The polygons are created in the shader ( it's all mathametical calculations) and put together to form an object and the more shaders you have the faster the frames are rendered and the better performance or quality of what the graphics card produces.
No, polygons per second and shaders are not the same thing. One is a processing measurement and the other a physical aspect of the GPU. What specific video cards are you considering?
